Mashable reports that the word, "Twitter" has been declared the most popular English word of 2009. The Global Language Monitor, which tracks language trends, has once again compiled and released its yearly list of the most popular words and phrases within the English language. In 2008, the #1 most popular word was “change” (referring to the mantra of the top name of 2008, Barack Obama). However, Obama has been supplanted this year by the 140 character sensation that is Twitter.
